Background: Although Fontan palliation seems to be inevitable for many patients with complex congenital heart defects (CHDs), candidates with appropriate conditions could be selected for biventricular conversion. We aimed to summarize our single-center experience in patient selection, surgical strategies, and early outcomes in biventricular conversion for the complex CHD.Methods: From April 2017 to June 2021, we reviewed 23 cases with complex CHD who underwent biventricular conversion. Patients were divided into two groups according to the development of the ventricles: balanced ventricular group (15 cases) and imbalanced ventricular group (8 cases). Early and short-term outcomes during the 30.2 months (range, 4.2–49.8 months) follow-up period were compared.Results: The overall mortality rate was 4.3% with one death case. In the balanced ventricular group, 6 cases received 3D printing for pre-operational evaluation. One case died because of heart failure in the early postoperative period. One case received reoperation due to the obstruction of the superior vena cava. In the imbalanced ventricular group, the mean left ventricular end-diastolic volume was (33.6 ± 2.1) ml/m2, the mean left ventricular end-diastolic pressure was 9.1 ± 1.9 mmHg, and 4 cases received 3D printing. No death occurred while one case implanted a pacemaker due to a third-degree atrioventricular block. The pre-operational evaluation and surgery simulation with a 3D printing model helped to reduce bypass time in the balanced group (p < 0.05), and reduced both bypass and aorta clamp time in the imbalanced group (p < 0.05). All patients presented great cardiac function in the follow-up period.Conclusion: Comprehensive evaluation, especially 3D printing technique, was conducive to finding the appropriate cases for biventricular conversion and significantly reduced surgery time. Biventricular conversion in selected patients led to promising clinical outcomes, albeit unverified long-term results.

The Creation

Advances in diagnostic imaging and 3D printing technologyhave enabled the creation of patient-specic models. Thisresearch established a wor kow for creating 3D printedcongenital hear t defec t (CHD) models, focusing specically oncreating aor tic arch models optimized for surgical planning andsimulation for hypoplastic left hear t syndrome (HLHS) stage Ipalliation. Novel methods for creating C T as well as 3Dultrasound and 3D fetal ultrasound derived prints were explored.

3D Printing Technology

Objective: To evaluate the usefulness of 3D printing patient-specific models of congenital heart disease (CHD) from the perspective of different stakeholders potentially benefiting from the technology (patients, parents, clinicians and nurses). Methods: Workshops, focus groups and teaching sessions were organized, each targeting a different group of stakeholders. Sessions involved displaying and discussing different 3D models of CHD. Model evaluation involved questionnaires, audio-recorded discussions and written feedback. Results: All stakeholders expressed a liking for the 3D models and for the patient-specific quality of such models. Patients indicated that 3D models can help them imagine “what’s going on inside” and parents agreed that these tools can spark curiosity in the young people. Clinicians indicated that teaching might be the most relevant application of such novel technology and nurses agreed that 3D models improved their learning experience during a course focused on CHD. Conclusion: The successful engagement of different stakeholders to evaluate 3D printing technology for CHD identified different priorities, highlighting the importance of eliciting the views of different groups. Practice Implications: A PPI-based approach in the evaluation and translation of 3D printing technology may increase patient empowerment, improve patient-doctor communication and provide better access to a new teaching and training tool.
